Going to the loo at night won’t give you cancer – but it could be a warning sign

by Cancer Research UK in Cancer Research UK - Science Update

Last week, The Daily Mail reported that ‘simply turning on a light at night for a few seconds to go to the toilet can cause changes that might lead to cancer’.
This might seem a far fetched link – and it is.
The researchers, based in Leicester and Israel, were studying the effects of interrupting animals’ sleep [...]... Read more »

Female fiddler crabs have sex with the neighbours

by Captain Skellett in A Schooner of Science


Fiddler crabs may be little, but they have one big appendage, the CLAW! A weapon if ever there was one. Like a lance or an over-sized boxing glove, something about it just screams MAN. So it fits that male fiddlers are the gender so endowed.
Females have two little feeding claws. No giant claw. No [...]... Read more »

Rotavirus vaccine and herd immunity

by iayork in Mystery Rays from Outer Space

Rotaviruses are one of the most common causes of gastroenteritis in children.  A new rotavirus vaccine was introduced a few years ago; what impact has it had on disease?

This study confirms on a national scale that the 2008 rotavirus season among children aged <5 years was dramatically reduced compared to pre-RV5 seasons.  …  [...]... Read more »

Of pigs, people and porcine polygenism

by Razib Khan in Gene Expression

Jared Diamond famously argued in Guns, Germs and Steel that only a small set of organisms have the characteristics which make them viable domesticates. Diamond’s thesis is that the distribution of these organisms congenial to a mutualistic relationship with man shaped the arc of our species’ history and the variation in wealth that we see [...]...

Water as an essential nutrient: the physiological basis of hydration

There are many times when the decision to say we need ‘8 glasses of water’ a day just pops out. But what is the evidence for this, do we need more or less? Obviously climate, activity, age and availability of fluids are all going to have an effect, and what about if we drink too much and suffer hyperhydration leading to hyponatraemia (a disturbance of the salts in the blood) in which the sodium (Natrium in Latin)........

'My son could be the next prime minister': How indirect bragging backfires

by BPS Research Digest in BPS Research Digest

You want to impress but you realise that bold-faced bragging can backfire. So instead you highlight the achievements of those close to you - perhaps your son or daughter's success, or even a colleague's - with the hope of basking in the reflected glory. 'I'm a lecturer at Neverland University,' you say, 'our head of department just won a Nobel Prize.' Bad move. According to Nurit Tal-Or's latest research on the psychology of boasting, this form of indirect self-promotion, known as 'burnishing', ........ Read more »

Is Memory for Music Special?

City dwellers of the future: Urban heat island warming may be as large as doubling CO2

by Phil Camill in Global Change: Intersection of Nature and Culture


In 1990, I remember driving on a freeway in Phoenix after midnight.  The temperature was a cool 102 degrees F after breaking the all time heat record of 126 F that day.  Deserts are good at cooling off at night.  But with all of the built environment in Phoenix storing heat from the day, the [...]...

Gloomy Octopii LOVE their HDTV!

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

I’ve got a special place in my heart for the Cephalopods.  These invertebrates have brought the spineless into the realm of charismatic megafauna, and this is not just because of their size.  Cephalopods, and octopii in particular, have large brains and complex visual capabilities.  Although the octopus eye evolved independently of the human eye, [...]...

Biodiversity, globalization and shifting disease ecologies

by DeLene Beeland in Wild Muse

As I was researching a story for the Observer, I had to go poking through the December 2009 issue of BioScience, and I stumbled across an interesting article reviewing biodiversity declines and global disease ecology. The authors assert that multiple factors working synergistically are leaving humans more at risk of contracting infectious diseases — [...]... Read more »

Faulty input makes you feel funny, but doesn’t hurt

by Lorimer Moseley in BodyInMind


There is a really attractive theory that has been used to explain why some people have chronic ongoing pain even though there is nothing wrong in the body part that hurts.  The theory suggests that the pain occurs because motor commands don’t match proprioceptive feedback from the body.  The name often given to this theory [...]...

How giant anteaters duke it out

by Laelaps in Laelaps



Two giant anteaters fight it out. On the left, the individuals lash out at each other with their enormous claws, and on the right they posture at each other (with the dominant animal, with the upright and puffed-out tail, on the right). From Kruetz et al 2009.




In the northern state of Roraima in Brazil, small plantations of the black wattle tree (Acacia mangium) serve up plenty of food to carpenter ants and other insects, and the variety of six-legged pests has attracted numerous giant ant........ Read more »

Aspirin Endorsed as Effective Agent in Migraine

by William Yates, M.D. in Brain Posts

Migraine headaches are a common type of severe headache that can cause significant episodic disability. The one-year prevalence for migraine is estimated to be 18% for women and 6% for men in the U.S. Headaches typically last from four to 72 hours and can interfere with work and interpersonal function.A recent Cochrane Review examined the effectiveness of aspirin. The review included a comparison between aspirin and more recently developed triptan drugs such as sumatriptin (Imitrex). Thirtee........ Read more »
